Romantic New Age books main inventory holds (14)

I believe the answer is:
sentimentalist
'romantic' is the definition.
(I've seen this before)
'new age books main inventory holds' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'age' becomes 'time' (an age is a period of time).
'books main' becomes 'senta' (I can't justify this - if you can you should believe this answer much more).
'inventory' becomes 'list' (I've seen this in another clue).
'holds' is an insertion indicator.
'senta'+'list'='sentalist'
'n'+'time'='ntime'
'ntime' placed into 'sentalist' is 'SENTIMENTALIST'.
Can you help me to learn more?
(Other definitions for sentimentalist that I've seen before include "Being overemotional" , "Nostalgic chap" , "Soppy person" , "One who's sloppy" , "Romantic" .)
